Yorkville Sound AM100 Acoustic Master 100W Combo Amplifier, Tested

Yorkville Sound AM100 "Acoustic Master" two-channel combo amplifier, designed and manufactured by Yorkville Sound of Toronto, Canada. Channel 1 offers instrument input with active/passive pickup switching, gain, three-band EQ, and a sweepable parametric notch filter; Channel 2 provides a combo XLR/TRS jack with gain and effects loop, ideal for vocals or a second instrument. The onboard 16-preset digital effects section covers reverb, delay, chorus, flange, pitch shift, and combination patches, eliminating the need for outboard pedals on a typical singer-songwriter rig. Cabinet is wrapped in dark blue-black carpet covering with molded metal corner protectors, top handle, and rubber feet; rear panel adds balanced XLR line out, Ch. 2 effects send/return, and footswitch jack. Power cord included.

CONDITION

Good condition and tested fully functional by staff. Carpet covering shows light scuffing and minor fuzzing at edges consistent with gigging use; panel graphics, knobs, and jacks remain clean and intact.
